Full Job Description

EXECUTIVE ASSISTANT TO THE CEO ABOUT LUMBRA Lumbra builds the vendor-neutral operating system for agentic AI in high-consequence environments. In our first ten months we won four fully competed prime contracts across the U.S. Government, every one of them deploying into classified spaces. We are live on JWICS. We were selected from a field of 200+ companies for a defense innovation challenge and won it. We beat two established defense primes on the same program and earned the follow-on, now in execution.

Aaron’s office runs on you. WHAT YOU’LL OWN - Own the CEO’s calendar, inbox, travel, and operating rhythm — the constant prioritization work that keeps the most consequential meetings from being squeezed by the loudest ones. - Prepare the CEO for meetings across USG principals, IC and DoD customers, primes, investors, frontier-lab partners, and recruits: briefing packets, pre-reads, and the situational context that turns a 30-minute meeting into a productive one. - Coordinate classified and customer-site logistics: visit requests, secure travel, base access, SCIF visit coordination, and the operational discipline that ensures the CEO arrives ready. - Handle sensitive information and communications with founder-level discretion: investor updates, board materials, personnel matters, and the steady flow of context running through a CEO’s offi
